Compare bands like Radiohead, R.E.M., Pearl Jam and U2 with bands like Live, Better Than Ezra, Cowboy Mouth, or Sister Hazel. Time has shown that there's a chance that the albums the first group puts out could sound much different than their last and that their live show will incoporate old stuff with new stuff. That second group includes some bands who are very entertaining at times but, as a friend of mine recently said about one band, "they basically just change the cover art on their albums." At this point in their careers, I find that second bunch of bands boring, for the most part.
Obviously opinions are like assholes, everyone has one. But let mine differ a little bit. I can agree with the point about the first batch of bands. In most cases they reinvent themselves, and something great comes out of it. I don't feel this is the case with Radiohead and Pearl Jam though. In my opinion, what they've put out recently stinks. Again just my opinion.
I can also agree about Cowboy Mouth and Sister Hazel. Both bands never really appealed to me at all, however CM intrigued me because there was something there. SH always sucked to me.
However, I will disagree about Live and BTE, Live especially. Everyone of their albums is distinctly different, and of course I feel some albums are better than others. But from their first album to their latest, things have changed on each release, however I feel that the latest album is trying to hard to get what they had originally. BTE hasn't differed as much, but "How Does Your Garden Grow" was a complete departure from what they did in the past, and I thought was rather good from an experimental point. And that album just went under the radar. However, their latest album "Butterfly" I believe it is, stinks. I just think it is a poppy piece of crap.
At other times, bands try and make a departure or reinvent themselves on future albums, and end up getting fired upon for it. People will say they aren't thinking about the fans, or that they are keeping true to their original sound. So what is a person to do? You're damned if you do, and damned if you don't. However, there is an audience out there for bands that stay the same, whether you think they are producing shit, or not. Their sound stays the same, for example Jimmy Buffett, Rush, Phish, many many current country acts. And they are all considered big successes beyond the commercial aspect.
Now I know that all of this is my own opinion, and I'm probably going to get fucking basted for this (since I am a fan of both Live and BTE) but oh well. People will disagree with my music tastes, as much as I disagree with theirs. That is what makes the music world go 'round, and why Britney Spears makes tons of money, and people with more talent than her in their fucking pinky make next to nothing.
Albeit, all of this now seems to have branched into another subject, maybe suitable for another forum, but I don't know.
